New Shower was connected to Toilet drain and now we get smell from shower drain.
Used baking soda a vinegar to clean drain, but smell continues to be present. Read that I should have the air vent checked to see if it's clogged, but I get no smell from the other shower leading me to think it's just the gas backing up from the pipes. Also, how does an air vent get clogged? Anyway, another suggestion is to pour a gallon of bleach into to shower drain and follow-up with hot water the next morning. If the contractor had put in a u-trap, I know the smell would not be an issue but the problem exists and ripping up the floor is not an option.
